The first commercial development of the ESEM in the late 1980s[32][33] allowed samples to be observed in low-pressure gaseous environments (e.g. 1–50 Torr or 0.1–6.7 kPa) and high relative humidity (up to 100%). This was made possible by the development of a secondary-electron detector[34][35] capable of operating in the presence of water vapour and by the use of pressure-limiting apertures with differential pumping in the path of the electron beam to separate the vacuum region (around the gun and lenses) from the sample chamber.

The dry specimen is usually mounted on a specimen stub using an adhesive such as epoxy resin or electrically conductive double-sided adhesive tape, and sputter-coated with gold or gold/palladium alloy before examination in the microscope. Samples may be sectioned (with a microtome) if information about the organism's internal ultrastructure is to be exposed for imaging.

The biggest problem that most people have when trying to learn anything to do with driving more traffic to their website or boosting their visibility across a variety of online mediums, is that they try to do the least amount of work for the greatest return. They cut corners and they take shortcuts. Because of that, they fail. Today, if you're serious about marketing anything on the web, you have to gain Google's trust.
Some search engines have also reached out to the SEO industry, and are frequent sponsors and guests at SEO conferences, webchats, and seminars. Major search engines provide information and guidelines to help with website optimization.[18][19] Google has a Sitemaps program to help webmasters learn if Google is having any problems indexing their website and also provides data on Google traffic to the website.[20] Bing Webmaster Tools provides a way for webmasters to submit a sitemap and web feeds, allows users to determine the "crawl rate", and track the web pages index status.

Nonconductive specimens collect charge when scanned by the electron beam, and especially in secondary electron imaging mode, this causes scanning faults and other image artifacts. For conventional imaging in the SEM, specimens must be electrically conductive, at least at the surface, and electrically grounded to prevent the accumulation of electrostatic charge. Metal objects require little special preparation for SEM except for cleaning and conductively mounting to a specimen stub. Non-conducting materials are usually coated with an ultrathin coating of electrically conducting material, deposited on the sample either by low-vacuum sputter coating or by high-vacuum evaporation. Conductive materials in current use for specimen coating include gold, gold/palladium alloy, platinum, iridium, tungsten, chromium, osmium,[13] and graphite. Coating with heavy metals may increase signal/noise ratio for samples of low atomic number (Z). The improvement arises because secondary electron emission for high-Z materials is enhanced.

Samples must be solid and they must fit into the microscope chamber. Maximum size in horizontal dimensions is usually on the order of 10 cm, vertical dimensions are generally much more limited and rarely exceed 40 mm. For most instruments samples must be stable in a vacuum on the order of 10-5 - 10-6 torr. Samples likely to outgas at low pressures (rocks saturated with hydrocarbons, "wet" samples such as coal, organic materials or swelling clays, and samples likely to decrepitate at low pressure) are unsuitable for examination in conventional SEM's. However, "low vacuum" and "environmental" SEMs also exist, and many of these types of samples can be successfully examined in these specialized instruments. EDS detectors on SEM's cannot detect very light elements (H, He, and Li), and many instruments cannot detect elements with atomic numbers less than 11 (Na). Most SEMs use a solid state x-ray detector (EDS), and while these detectors are very fast and easy to utilize, they have relatively poor energy resolution and sensitivity to elements present in low abundances when compared to wavelength dispersive x-ray detectors (WDS) on most electron probe microanalyzers (EPMA). An electrically conductive coating must be applied to electrically insulating samples for study in conventional SEM's, unless the instrument is capable of operation in a low vacuum mode.


Many marketers think of search engines as delivering the search results or SERP (Search Engine Results Page) in the form of purely textual results. The truth is that search results can be any mix of text, images, video, audio, or other file formats. In the United States, search engines don’t simply include Google, Yahoo and Bing; they also include commerce sites such as eBay and Amazon, as well as specialty search engines such as YouTube and Hulu for video, restaurant search engines, "people" search engines such as LinkedIn, or online business directories for local results, including IYPs (Internet Yellow Pages) and sites such as Yelp, Angie's List, and others.
Once you understand how everything works, and your expectations are set the right way, decide what you want to do. Do you want to become an affiliate marketer? Do you want to be a network marketer? Do you want to become a blogger and sell your own products? Squeeze pages, which are glorified sales pages that attract people and direct their attention towards a single action of providing their email address, are created in a variety of methods. The better they are, the more likely they'll convert.
The next step? How will you communicate with people. Sharpe says that you need to decide on this early on. Will you blog? Will you use social media? Will you build a list by working with solo ad providers? Will you place paid advertisements? What will you do and how will you do it? What you must realize here is that you have to get really good at copy writing. The better you get at copy writing, the more success you'll find as an internet marketer.
The criteria and metrics can be classified according to its type and time span. Regarding the type, we can either evaluate these campaigns "Quantitatively" or "Qualitatively". Quantitative metrics may include "Sales Volume" and "Revenue Increase/Decrease". While qualitative metrics may include the enhanced "Brand awareness, image and health" as well as the "relationship with the customers".

Video Marketing is a good way to promote your business. However, it’s not that an easy task and sometimes you need a help from your co-workers like graphic designers if you don’t know how to create or draw your own icon or image to be used in the video. Though you can get from free stock photos and icons sites to compile it for your video, I think it’s better if you create your own.


Being a leading data-driven agency, we are passionate about the use of data for designing the ideal marketing mix for each client and then of course optimization towards specific ROI metrics. Online marketing with its promise of total measurement and complete transparency has grown at a fast clip over the years. With the numerous advertising channels available online and offline it makes attributing success to the correct campaigns very difficult. Data science is the core of every campaign we build and every goal we collectively set with clients.
Sixty-five percent of business decision-makers visit a marketer’s website after viewing a branded video. It’s clear that quality and relevant video marketing content can dramatically improve your site’s SEO by driving people to your homepage. Additionally, video can enhance your conversion rates: HubSpot reports that 39% of business decision-makers contact a vendor after viewing a branded video. https://m.youtube.com/watch?feature=player_embedded&v=7bNPg8UbhaE
Video advertising is becoming more and more affordable and widespread. Video adoption grows partly because advances in technology but also because it’s easy to spread across the globe. Making marketing videos for your business requires creativity and knowledge of human psychology. The cocktail of these components makes it possible to create real miracles of advertising at minimal cost. https://youtube.com/v/7bNPg8UbhaE
